Site survey tool for cellular base station placement

Abstract:

Apparatuses, methods, and systems for a site survey tool are disclosed. One site survey tool includes an elevated platform, wherein the elevated platform includes a directionally adjustable beam-forming antenna, wherein the elevated platform operates to adjust an elevation of the adjustable beam-forming antenna, and wherein the elevated platform operates to transmit or receive wireless signals while the directionally adjustable beam-forming antenna changes a beam direction. Further, a ground unit transmits wireless signals to the elevated platform or receives wireless signals from the elevated platform while the directionally adjustable beam-forming antenna changes the beam direction. A signal quality of received wireless signals is measured, and a power azimuth angular spectrum of a surveyed site is estimated based on a known motion of the adjustable beam-forming antenna, a known beam-forming pattern of the adjustable beam-forming antenna, and the measured phase and amplitude of the received wireless signals.
